National Geographic Glow-in-the-Dark Marble Run - 50pcs

Get ready for glowing, fast-paced fun with the National Geographic Glow-in-the-Dark Marble Run!

This 50-piece set lets kids design and build their own marble racetracks using interlocking pieces that snap together securely. As glowing marbles twist, turn, and race down the track, kids will be amazed watching their creations come to life, especially when the lights go out.

The set includes glow-in-the-dark marbles and a UV light keychain to make them shine bright as they zoom toward the finish line. A full-color learning guide introduces kids to the science behind their builds, teaching key concepts like gravity, motion, and basic engineering in a hands-on, easy-to-understand way.

With endless track configurations and compatibility with other National Geographic marble run sets, the fun and learning never stop. Designed for kids ages 8 and up, this engaging STEM activity encourages creativity, problem-solving, and hours of exciting play.
